该研究估计了2009/2010年中国西南部干旱对工业产出和二氧化碳（CO2）排放的影响。我们关注电力和能源密集型行业的产出，并调查在这场极端干旱期间火电替代水电的情况。2006年至2013年，93，830家公司的面板数据被用来检查他们对这一极端气候事件的反应。我们发现，严重的干旱减少了水电生产以及能源密集型部门的经济产出，而它增加了火电企业的发电量。2009 - 2013年，西南地区CO2净排放量增加670.4364万吨，约占区域CO2排放总量的0.64%。这些发现表明，气候灾害可能会增加碳排放，从而导致气候变化。
The study estimates the impact of the 2009/2010 drought in southwestern China on industrial outcomes and carbon dioxide (CO2) emissions. We focus on the outputs of the power and energy-intensive sectors and investigate the substitution of thermal power for hydropower during this extreme drought. Panel data for 93,830 firms from 2006 to 2013 were used to examine their responses to this extreme climatic event. We find that severe drought reduced hydropower production as well as the economic output of energy-intensive sectors, while it increased the power production of thermal power firms. As a result, the net CO2emissions in the southwest increased by 6,704,364 tons, about 0.64% increase of the total regional CO2emissions each year from 2009 to 2013. These findings suggest that climate disasters may increase carbon emissions, thereby contributing to climate change.
